Tour schedule might differ due to weather and sea conditions. The buffet lunch is limited for vegetarian people: Rice with vegetables and fruits. Rain in Southern Thailand is unpredictable. Even if it rains, the tour is guaranteed to happen if conditions are safe, and no refund will be granted. Rainfall is usually short. We need to check front of the Emerald Cave if we can go. If waves are too high, the cave cannot be entered, this is out of our control. You need to swim through a narrow dark cave of 80 meters to reach the lagoon. The longtail boat engine is rather loud and there is quite some travel time to get to the 4 islands and back. The Andaman sea is a rough sea with usually big waves and it might be a bumpy ride. Please prepare a pill for seasickness if you have a sensitive stomach. Minimum age of participation is 2. No pregnant women allowed in this experience due to safety reasons. Maximum 27 people are allowed on 1 boat.
